Come on, you're smarter than that. There's nothing magical about having an advanced degree. As you understand full well, having a doctorate in English or quantum physics or medicine is irrelevant to one's qualifications in global environmental issues. If the list is 17,000 people with no selectivity based on environment, then it could just as well be a phone book.
If you want to support your point, find qualified environmental scientists who discount global warming.
Apparently, nobody actually went to the website and read a thing:
Signers of this petition so far include 2,660 physicists, geophysicists, climatologists, meteorologists, oceanographers, and environmental scientists (select this link for a listing of these individuals) who are especially well qualified to evaluate the effects of carbon dioxide on the Earth's atmosphere and climate.
Signers of this petition also include 5,017 scientists whose fields of specialization in chemistry, biochemistry, biology, and other life sciences (select this link for a listing of these individuals) make them especially well qualified to evaluate the effects of carbon dioxide upon the Earth's plant and animal life.
Of the 19,700 signatures that the project has received in total so far, 17,800 have been independently verified and the other 1,900 have not yet been independently verified. Of those signers holding the degree of PhD, 95% have now been independently verified.

Actually, it was the environuts who called anyone signing their 'Global Warming Letter' a "scientist":
Claim: Thousands of scientists have signed letters and petitions alerting the public to the dangers of global warming.
Fact: One of the letters often cited to support this claim was issued by Ozone Action. A close examination of that letter revealed that only 10% of the letter's signatories had backgrounds in climate science. Worse, the signatories include two landscape architects, ten people with backgrounds in psychology, one person trained in traditional Chinese medicine techniques and one person trained in gynecology. There is a world of difference between a gynecologist and a climatologist.
Since the climate treaty was hatched in Rio de Janeiro in 1992, scientists have shown their dissent with
four petitions: the 1992 "Statement by Atmospheric Scientists on Greenhouse Warming," with more than 100 signatures; the 1992 "Heidelberg Appeal," with
more than 4,000 signatures; the 1996 "Leipzig Declaration," signed by some 130 prominent U.S. climate scientists, including several who participated in the U.N. Intergovernmental Panel on Climate Change (IPCC); and, this year, the "Oregon Petition" which has been signed thus far by 17,000 U.S. scientists.
A survey of over 400 German, American and Canadian climate researchers conducted by Dennis Bray of the Meteorologisches Institut der Universitat Hamburg and Hans von Storch of GKSS Forschungszentrum and reported in the United Nations Climate Change Bulletin, for example, found that only 10% of the researchers surveyed "strongly agreed" with the statement "We can say for certain that global warming is a process already underway."
Further, 35% of those surveyed either disagreed with the statement or were undecided.
Perhaps even more interesting, 67% of the researchers either disagreed or were uncertain about the proposition that climate change will occur so suddenly that a lack of preparation would devastate certain parts of the world -- the underlying assumption on which the talks in Kyoto, Japan were based.
Close to half of the researchers -- 48% -- indicated that they don't have faith in the forecasts of the global climate models, the strongest argument in favor of quick, decisive, international action to counter the threat of global warming. Another 20% expressed uncertainty about these models.
There is no consensus among qualified scientists on Global Warming.
